The sides of the opening 6 and the forward portion of the bore 4 areprovided with grooves 14, as shown in Fig. 5, to form ways for guidingthe movement of the staples 9' as they are drawn within the openingG,the said i grooves 'communicating at one end with the transverseI groove8 and terminating at their other end at a point in the plane of the bore4. To enable the legs of a staple 9' to have a circular movement as thchead thereof follows the course of the grooves 14, thelongitudinally-alining portions of the abutment 12 are suitably boredto'a depth indicated by the curved line 15, thereby enabling the ends ofsaid legs to drop into the opening 7 in advance of the lower edge ofsaid abutment, as

' shown in Fig. 5.

The tingerl() is adaptedt i be held in proper position within the member2 by means of the spring-pressed dog 16, which is pivoted in said memberand has its free end bearing against the upper side of said finger.

A knife 17, which is mounted in and has its movement guided by alongitudinal groove 1T', provided in the upper surface of the block 2,in parallelism with the bore 4, has one end rigidly attached to theouter end of the plunger by al connecting-block 18 and its other endprovided with a cutting edge which is adapted to operate over the end ofthe apertured plug 19, through which the wire 9" is fed, and to seversaid wire just prior to the limit of forward movement of the plunger 5.As the desired length of wire is fed through the plug 19 its upperend isdefiected laterally of the block Q by means of the inclined way 20, inposition to fall into the groove 8 as soon as it is severed by the knife17. clined guides 21 are provided at the outer end of the groove 8 toinsure the severed section of wire falling therein.

A die 22, which has its clamping-surfacel tapered to adapt it to coactwith the tapered discharge end' of the block 2, is carried by themovable table 3 and caused to be moved into and out of engagement withthe end of said block as the weaving operation requires.

Having thus described the parts comprising our invention, we will nowdescribe the mechanism shown in the drawings for intermittently feedinga wire thereto and actuating the movable parts thereof.

Motion is transmitted to the shaft 23, which is mounted in the frame 1,and to the spurgear 24 thereon from any suitable power and iscommunicated from said gear to the gears 25 and shafts Q6, which aremounted at either end of said frame through the medium of theidler-pinions 27. Eccentrics 28 are employed for communicating areciprocatory movement from the shafts 26 to the block 18, to which theplungerand knife l'are attached,

eccentric-ro ^ls 28' and the links 2i). the latter pivotally connectingsaid rods with a boss 30 ateither end of the frame land the associatedblock or table. As the receding movement of the table 3 and die 22 needbe only sufficient to enable the fabric .being woven to freely passbetween the coacting faces ofthe block :2 and said die as it isintermittently wound, we employ an eccentric for that pur pose having aless radial swing than the one employed for reciprocating the plunger 4and knife 17.

' The wire 9" is caused to be intermittently fed to the block :2 by thefeed-wheels 31 and 32. the former. together with the rigidly-connectedratchet 33, being loosely mounted on the rock-shaft 34 and the latterbeing mounted on the oscillatory lever 35, as shown. An oscillatorymovement is imparted to theshaft `34 from the block 18 through themedium of the -arm 36 on said shaft and the rod 37, which latterconnects with a boss 18' on said block.

The-proper movement is in turn imparted tov i the feed-wheel 31 from theshaft 34 by means of a pawl 33', which is carried by an arm 38 on saidshaft, engaging the teeth of the ratchet 33 and causing it to be rotateda predetermined distance at each forward movement of the block 18. Thelever 35, on which the feedwheel 3Q is mounted, is fulcrnmed toa bracket35', secured to the frame 1, and is caused to normally hold saidfeed-wheel in contact with the companion wheel 31 by reason of the eX-pa'nsion-spring 39, which is interposed between the end of said leverand a portion of the frame 1, as shown in Fig. 2.

A propel' length of wire 9" is-caused to be intermittently fed to thestaple-forming parts by reason of the upper end of the lever 35 beingengaged by a button 40 on the rod 41 at a vpredetermined point in themovement of the'block 18, thereby causing the lever to be IOO IOS ioscillated and the feedwheel 32 drawn out of engagement with thecompanion wheel 31 as soon as the required length of .wire has been paidout. The rod 41 has one end pivotally connected to the arm 38 on theshaft 34, from which it receives its reciprocatory motion, and its otherend secured to the swinging arm 42, which is pivoted to the frame 1.

@In the operation of our invention the revolving of the eccentrics 28causes a properlytimed simultaneous receding movement of the table 3 andplunger 5, the former receding to permit the fabric being woven to be`passed between the coacti ng faces of the block Qand die 22 in order tobring the next alining intersecting portion thereof in position to be.stapled and the latter receding for the purpose of operating the finger10 to draw an engaged section of wire within the openingt 65 and to thetable 3 and are connected to said l about the alined intersectingportion of the ius- ' section of wire 9 is fe'd to the inclined way lfabric on the return movement of said plunl ger. During the dischargeand clamping of lthe staple 9' about` the fabric being woven a 20 andsevered by the knife 17 just prior to the limit of Aforward movement oflthe pluuger 5, the severed section 9 falling across the upper side ofthe finger 10, which is then in the position shown in Figs. 1, 4, and 6.It g will thus be seen that as soon as the finger 10 l has retreatedwithin the opening cariving the previously-'severed section 9 therewith,the i upper wire 9 will drop into the groove 8 in proper position to beengaged by said plunger on its return movement. The interruption of thecontact of the feed-wheels 31 and 32 and the movement of the knife 1Tare so i timed that the feed of the wire 9" will be stopped just priorto the contact of the knife therewith.

In Figs. '7, 8, and 9 of the drawings are shown different operativepositions of one] modified forni of our invention, in which- Arepresents the stationary block containing the staple forming anddischargingr parts; B, a circular way or opening into which the sectionof wire is drawn for the purpose of forming it into U shape; C, anoscillatory sector or member that is-pivoted to the block A at a pointbelow said circular wayB and concentric therewith; l), a wire-engagingfinger which is pivoted to the outer portion of the member C and adaptedto engage and draw a section of wire D' within the way B on the rearwardmovement of said memberand form it into U shape, and Ea tongue that issecured to the member )substantially as shown and adapted to be operatedin the way B for discharging the formed staple from the block A andclenching it about an alining object on the return movementof saidmember. A properly-timed oscillatory movement is imparted to the memberC from areciprocatory rod F, which connects therewith through the mediumof the link G and receives its movement from any suitable means.

A somewhat similar construction to that just described is illustrated inFigs. 10, 11, 12, and 13 of the drawings. In this construction arepresents the stationary block in which the operative parts of theinvention are mounted; the staple-forming finger, which is formed withthe laterally-projectiug pins c for riding in the grooves c', providediu the block t at either side of the path of movement of said finger; d,the plunger, which operates within the circular way fl' to discharge andelench the-staple when formed, and e a block which has connection withsaid finger and plunger and is actuated by suitable mechanism (notshown) to communicate the required movements thereto. In the operationof this latter device the wire-feed mechanism is timed to begin to feedthe wire to the rear of the hook of the finger in an intersecting lplane therewith as soon as said finger has reached its limit of `forwardmovement, which is prior to the limitof' forward movement of the plungerJ. B v the time the plunger'd has reached its limit of forward movementand returned a distance sufficient for the lugv f, formed on its uppersurface, to engage an alining projection on said finger, as shown inFig. 10, a proper length of wire for forming the staple has been fed tothe block 'a and severed and left in position to be drawn within thecircular way d' and formed into U shape on the receding movement of saidfinger, as shown in Fig. 11. On the forward movement of the linger andplunger (Z thewireengaging end of. the former remains in advance of theend of the plunger, as shown in Fig. 11, until the forward end of saidfinger engages the alining abutment .f/ on the block a and is forcedthereby out of the path of the c' plunger, a slight oscillatory movementof said finger being permitted at this point by reason of the forwardpins c thereon entering the enlarged portion It of the grooves c',asshown by dotted lines in Fig. l2.

'hile it has been necessary in the description and drawings illustratingour invention to show and describe some means for operating thestaple-forming mechanism` feeding the wire thereto, and severing thesame, it will be obvious that numerous methods of performing theseseveral functions might be devised without detracting from the merits ofour invention, which consists of the provision of a single-plungerstaple forming and discharging mechanism and the operative associationof such mechanism with the weaving parts of a wire-fabric machine, andalso that such changes in the form, proportion, and minor details ofconstruction of the parts as fairlyv fall within the scope of ourinvention may be made without departing from the spirit or sacrificingany of the advantages thereof. lt is also apparent that as many of thestaple-forming machines may be employed in a loom as there arewarp-wires in the fabric being woven, one being mounted at eachintersection of a freshly-fed Woof-wire with a warp-wire.
